MACHINE FOR TREATING HIDES, SKINS, AND LEATHER.

Application filed May 25, 1922.

This invention relates to cutting machines and is herein disclosed as embodied in a shaving machine provided with a rotatable, bladed cylinder adapted to shave hides, skins and leather and with a rotary grinder reciprocated relatively to the bladed cylinder and operative to keep the blades of the cylinder sharp.

It is an object of the invention to provide a shaving machine capable of doing a superior grade of" work which at the same time will have an increased output and efficiency and will be inexpensive to construct and maintain.

Vith this object in view, the bladed cylinder, which is characteristic of shaving machines of this type, is directly connected to a driving motor, the rotor of the motor being mounted upon the shaft of the cylinder,

This practically eliminates chattering and vibration of the bladed cylinder and, accordingly, produces superior work free from the objectionable markings of the skins wh ch are a not infrequent incident of the shaving operation as performed by the machines of the prior art. The illustrated machine, 1n accordance with current practice, is also provided with a rotary grinder reciprocated lengthwise of the bladed cylinder and arranged to sharpen the blades of the cylinder. In accordance with the present invention, this grinder also is directly connected to an electric motor arranged to reciprocate with the grinder and having its rotor mounted on or directly connected to the shaft of the grinder. Since the other power-operated parts of the machine are driven from one of these motors, it follows that the machine constitutes a self-contained unit capable of being installed anywhere in a factory or tannery even though the building is not provided with shafting.

With the above and other objects and features in view, the invention will now be described with reference to the accompanying drawings and pointed out in the claims.

In the drawings Fig. 1 is a front'elevation of a shaving machine embodying this invention. i

Fig. 2, a plan of the machine shown in Fig. 1 with parts broken away.

Fig. 3, a side elevation looking toward the right in Fig. 2, and

Serial No. 563,617.

Fig. 4, a side elevation looking toward the left in Fig. 2.

The shaving machine herein shown as embodying this invention is provided with a bed roll 10, a bladed cylinder 12, a grinding wheel 13 and a reciprocating carriage 14 for the latter, substantially as in machines of this character now commonly in use. In accordance with the present invention, the bladed cylinder 12 is driven by an electric motor 15 mounted on a bracket 16 attached to a side upright 17 of the framework of the machine.

The shaft 18 of the bladed cylinder 12 is extended through long bearings 19, 20 attached to the side uprights 17 of the frame work of the machine, and said shaft has directly attached to it in any suitable manner, the rotor or armature of the motor 15.

The shaft 18 beyond the bearing 20 has mounted on .it two pulleys 21, 22, the pulley 21 being connected by a belt 23 with a pulley 24 on the shaft'25, by means of which the carriage 14 carrying the grinding wheel 13 is reciprocated in a manner well understood and common to machines of this character.

The pulley 22 is connected by a belt 28 with a relatively large pulley 29 on a shaft 30 mounted in the framework and provided with a smaller pulley 31, see Fig. 4, which is connected by a belt 32 with a pulley 33 on the shaft of a rotary brush 34, which is located below and cooperates with the bladed cylinder 12 to keep the latter free from chips, dust, etc.

It will thus be seen that the electric motor 15 acts as a source of power for the bladed cylinder 12, for the reciprocating carriage 14 which carries the grinder, and for the brush 34.

Provision is made for rotating the grinding wheel 13 at a relatively high speed its carriage 14 is reciprocated in a path parallel with the axis of the bladed cylinder 12. To this end, a relatively small electric motor 35'is supported in a bracket or frame 36 attached to the grinder carriage 14 and said motor has its rotor 37 mounted on the shaft 38 of the grinding wheel 13. The framework of the machine is provided with a suitable base 40 and the bed roll 10 is mounted in levers 41 which are operated by a foot t-readle 42 to move the bed roll with the work thereon with relation to the bladed cylinder 12, and the depth of the cut made by the bladed cylinder is controlled by the operator pressing more or less upon the treadle, the same asin shavingmachines now in use in tanneries or factories.

From the above description it will be seen that the bladed cylinder 12 is revolved at a relatively high speed by the electric motor 15 without vibration or chattering of the bladed cylinder 12, and as a result asupcrior grade of work is obtained, inasmuch as marking or otherwise injuring the work by chattering of the bladed cylinder is avoided. A'lsothe relatively high speed of the bladed cylinder enables a greater number of skins tobe shaved in a given time.

Furthermore it will be observed that each machine isa self contained unit, having its own motive power and istherefore capable of beinguplacedin any suitable or desired roomorplace in a factory or taunery, as its operation does not depend upon the usual shafting. The .electric motors 15,735 are supplied with current in any suitable or known .manner.

.It will also be observed that by directly drivingthe bladed cylinder 12and the grindingrwheel 13 by the electric motors 15 and 35 respectively, which are supportedby the framework of themachine, and by utilizing the shaftofthe bladed cylinder for driving the shaft which effects reciprocation ofthe carriage carrying the grinding wheel, and also .for driving the rotary brush for the bladed cylinder, the machine is materially simplified and its cost of construction and maintenance materially reduced.

=Oneembodiment ofthe invention is hereinshown, but it is .not desired ,to limit the invention toithe particular construction shown.
